To all whom it may concern-.-

Be it known that I, CHARLES \V. JONES, a citizen of the United States, residing at Lon don, in the county of Middlesex an d Province of Ontario, Canada, have invented certain new and useful Improvements in Spindle- Driving-Meehanism for Spinning-Machines, of which the following is a specification.

My invention relates to spindle driving mechanism for spinning-machines5 and it consists in a novel construction and arrangement of the banding and the tension devices applied to the band, whereby a uniform tension is maintained.

In the drawings,Figurelis a top plan,with portions removed, of a part of a spin ningframe, showing my invention applied thereto; Fig. 2, a sectional view taken at right angles to the axis of the driving-drum; Fig. 3, a sectional view on the line 3 3 of Fig. 2. and Fig. 4 a sectional view of the tension-pulley.

A indicates the driving drum or roller B B B, the spindles; a a d, the whirls, and C the endless driving-band passing alternately about the drum and spindle-whirls. The top of the drum is about on line with the whirls, so that the upper portionco'f the banding will be approximately horizontal and will be separated a distance from the lower portion d, which inclines downward from the whirls to the lower side of the drum, as shown in Fig. 2.

D indicates what may be termed the return-line, which forms a part of the drivingband, the return -line extending forwardly from the whirls of the end spindles and passing across the machine between the upper and lower portions 0 (Z of the banding, as shown in Figs. 1 and 2.

Secured to the top board E, placed above the drum A, is a bracket or support F,which in the present instance is madein the form of a hollow socket-piece or sleeve, which is designed to receive and support one end olf a bar G, as shown in Figs. 1 and 2, the opposite end of the bar being supported by the top board H, through which the spindles pass, or bya link or arm I), secured to said top board H.

The bar or support G will preferably, though not necessarily, be made rectangular in cross-section. (about three eighths of an inch square) and will advisably be arranged with one of its edges uppermost, as clearlyindi cated in Fig. 3, the bracket orsupport F being correspondingly shaped.

The bar G is designed to be moved into and out of the bracket orsupport F, in orderthat the device may be applied to different styles and sizes of machines.

Mounted loosely upon the bar or support G, so as to slide freely back and forth thereon, is a sleeve or hollow block I, whose form in cross-section corresponds to that of the bar, and depending from the sleeve is an arm 6, carrying atits lower end a grooved wheel of about the same diameter as one of the whirls a, to receive the return-line D.

Secured to the sleeve or block I is a cord g or other flexible connection, which extends rearward and passes over a guiding-wheel h, secured to the socket-piece or bracket F, as shown in Fig. 2, the end of the cord or con nection being secured to a coiled spring *6 or to any equivalent device that will maintain the necessary tension upon the cord g.

In the foregoing description I have only referred to one bar G, which,when one bar only is employed, would be placed at a point midway between the ends of the drum, and Fig. 2 may be considered as representing such an arrangement. Of course where a large number of spindles is employed-say, from sixty to one hundred it will be better to employ twoor more of such bars, as represented in Fig. 1, as otherwise the sagging of the return-band during the reversal of travel might possibly cause the return-band to rub against the lower portion dot the banding. here two bars are employed they will be made alike, and each will have its own spring or equivalent tension device. Bycarrying the returnline between the upper and lower portions 0 cl of the banding proper and applying the tension devices from above, as it were, instead of from beneath, as has been the more common custom, I secure an exceedingly compact arrangement and one that is easilyaccessible when it becomes necessary to make repairs. In machines having no bottom board, or an open bottom board, itis particularly valuable. Furthermore, there are no braces or supports against which the band is apt to rub, as is the case where the tension devices are applied beneath the drum or to other parts of the bottom board.

The device herein shown and described is exceedingly simple and cheap, and applicable with little or no labor to any style of machine. The grooved wheel f, before referred to, will be provided with a central oiling-chamber j, through which the arm or spindlee passes, as shown in Fig. 4. To form this chamber j the hub of the wheel is first bored out and a washer or disk 7t, preferably of vulcanized fiber, is forced into each end of the opening and frictionally held therein, the two disks or washers being separated one from the other, as shown. After the disks are forced to place I drill a hole through them of considerably less diameter than the diameter of the hole or opening of the hub; but, if desirechthe disks may be drilled before being forced to place. By arrangingthe bar G with one of its edges uppermost the sliding block will move or slide practically upon a knife-edge.

Having thus described my invention, what I claim is 1. In combination with driving-drumA and spindles B, driving-band C, passing alternately about the spindles and drum and havingareturn-line D, a bar G, supported above the driving-band, a sleeve I, mounted upon the bar and having a depending arm e and pulley f, the latter receiving the return-line, a flexible connection g, attached to the sleeve, anda spring or equivalent tension device '6, acting upon the connection, all substantially as shown.

2. In combination with drum A, spindles B, and driving-band 0, arranged substantially as shown, top boards E and H, a bar G, supported at its ends by the top boards, a sleeve or block I, mounted upon the bar and provided on its lower side with a pulley f to receive the driving-band, and a tension device connected with the sleeve.

3. In combination with drum A, spindles B, and driving-band O, passing alternately about the spindles and drum, a rigid bar G, located above the driving-band, a tension-wheel supported by the bar and extending downward between the upper and lower portions 0 cl of the driving-band in position to receive the return-line of the latter, and a tension device applied to the pulley, all substantially as shown and described.

4. In combination with drum A and spindles B, driving-band 0, having a return-line D, top boards E and H, a bracket or socket F, secured to board E and provided with a wheel h, a bar G, fitting into the socket and supported at its opposite end by a link I), sleeve I, provided with arm e and pulley f, cord or connection g, and spring '5. all arranged substantially as shown.

5. In combination with drum A, spindles l3, and drivingband 0, arranged substantially as shown, angular bar G, arranged with one of its edges uppermost, and a sliding block carrying a tension-pulley, mounted upon the bar.

In witness whereof I hereunto set my hand in the presence of two witnesses.

CHARLES W. JONES.
